ause Mark is older, he receives $20 for each mowing job and Ryan receives $15. The brothers’ parents pay for the fuel used to mow, so all of the money the brothers earn goes to savings.
Write two equations, one for Mark and one for Ryan, to represent the money in savings (s) based on the number of mowing jobs (j) Mark and Ryan do.

Answer:

  • 30 jobs

Step-by-step explanation:

<u>Mark</u>

  • Initial amount - $200
  • Earning - $20*j
  • Saving is: S = 20j + 200

<u>Ryan</u>

  • Initial amount - $350
  • Earning - $15*j
  • Saving is: S = 15j + 350

<u>If they get same saving, then the equations will be equal:</u>

  • 20j + 200 = 15j + 350
  • 20j - 15j = 350 - 200
  • 5j = 150
  • j = 150/5
  • j = 30

The answer is 30 mowing jobs

Answer:

y = -4

x = 3

Step-by-step explanation:

Let's first explain when x = 0

Find where x = 0 on the graph. We are finding what the y-value would be. Trace down the y-axis along the vertical line x = 0. Where does the line intersect the y-axis when x = 0? The answer would be -4

The y-intercept is -4, and the x-value for this is 0, of course. So the correct answer for when x = 0 would be y = -4.

Next, we are told to find x when y = -2. Find where y = -2. Now, staying at y = -2, go horizontally along the x-axis at y = -2 until you reach the line. Boom! You should have connected up with the line at around x = 3. Therefore, when y = -2, x = 3

Flura [38]

Answer:

If the game with 3 hits is ignored the data becomes:

  • 7, 7, 8, 8, 8, 8, 9, 9, 9, 9, 9, 10, 10, 10, 10, 11, 11, 11, 11

a) The mean will increase.

<u>With 3:</u>

  • (3 + 7*2 + 8*4 + 9*5 + 10*4 + 11*4)/20 = 8.9

<u>Without 3:</u>

  • (7*2 + 8*4 + 9*5 + 10*4 + 11*4)/19 = 9.21

b) The median will remain as is.

  • With 3 and without the median is same = 9

9514 1404 393

Answer:

  • 33, 27
  • 285

Step-by-step explanation:

The price difference is found by subtracting Emma's price from DeShawn's price. Each price is the product of the number of square feet and the price per square foot.

The number of square feet is already given in the answer form, so you only need to fill in the per square foot prices. Those are found in the table. Both the window name and the window area give clues as to which is the right price to choose.

The expression is (4² × 33) - (3² × 27).

__

For the second fill-in, you need to actually do this arithmetic. For many calculators, you can enter this expression directly.

DeShawn paid $285 more for his window than Emma.
